WAVELET ANALYSIS OF OSCILLATING MOTIONS IN AN OSCILLATING HEAT PIPE

摘要

The heat to be removed from the electronic components or systems can be used to excite the oscillating motion of a train of liquid plugs and bubbles in the oscillating heat pipe (OHP). The oscillating motion in the OHP can significantly enhance heat transfer. The wavelet transform (WT) analysis is used to analyze the oscillating motions occurring in the OHP. It is found that a number of waveforms exist, which indicates that the oscillating motions in an OHP are resulted from a number of sources. Results of the investigation will provide a better understanding of oscillating motion mechanisms occurring in the OHP.
